Bhagavad Gita · 9.14

सततं कीर्तयन्तो मां यतन्तश्च दृढव्रताः।नमस्यन्तश्च मां भक्त्या नित्ययुक्ता उपासते॥

satataṁ kīrtayanto māṁ yatantaśh cha dṛḍha-vratāḥ namasyantaśh cha māṁ bhaktyā nitya-yuktā upāsate

Always chanting My glories, striving with firm resolve, bowing down to Me with devotion, they worship Me, ever united in yoga.
